Abstract:

The chemical pollution of water is one of the major environmental problems in today’s world, since polluted water poses a threat to wildlife, as well as to human health and welfare, given that it hinders the sustainable development of both society and economy. Dye effluent from textile industry is one of the most important sources of environmental pollution. Heterogeneous photocatalysis is one of the most rapidly expanding methods used for water treatment. The main objective of this project is the development of some novel photocatalysts with ZnO doped micro-/nanoparticles with high efficiency under UV and visible light, intended for waste water treatment by economical and time-efficient technology. The project activities will focus on the preparation of novel micro-/nanostructured materials with photocatalytic activity, containing ZnO-doped particles as fillers for new, as well as well-known, polymer matrices. The composites will be obtained via photochemical polymerization, and then thoroughly characterized as to establish their structure-properties relationships. The selection of polymer matrix and the polymerization technique represents some of the key elements of this project. For this purpose, the material will be inert, semitransparent, inexpensive, and durable. The proposed research envisages some specific objectives, as follows: preparation of micro-/nanoparticles, synthesis of ZnO particles of various sizes; doping with different metals; particles characterization. Design and synthesis of new (meth)acrylic monomers for photopolymerization reactions. Development of novel hybrid materials containing ZnO and/or ZnO-doped micro-/nanoparticles: preparation of composites; in-depth characterization of the hybrid materials. Study of the photocatalytic effectiveness of the new hybrid catalysts by comparatively assessing the photochemical degradation of some dyes in their presence, under UV and visible light exposure.

Abstract:

Subscribing to HORIZON 2020 "Innovation" area, SMARTCrom project aims at working on a multidisciplinary and very hot topic - smart materials by introducing the "smart" concept in the field of heterocyclic polymers. The basic project idea is the development of smart materials with chromic response to external stimuli, such as electrical potential, metal ions, or light radiation. The key approach relies on the dynamic polymers engineering by preserving the same (or related) polymer backbone structure while the receptor is a variable, so as to obtain versatile side chain polymers. The heterocyclic polymers will be mainly high performance polyimides that will be modified as to carry the receptor: 15-crown-5/18-crown-6 as receptor for alkaline metals, bipyridyl/phenanthroline as receptor for heavy metals, triphenylamine or heterocyclic derivatives as receptors for the electric potential, and azobenzene moieties as receptors for the light radiation. The new macromolecular architectures will include an optimum combination of heteroaromatic, aromatic or cycloaliphatic units in the same structural unit of the polymer receptor, so as to provide the desired chromic response to a particular stimulus, or even to more stimuli. The original research will focus on: modeling of macromolecular architectures with adequately functionalized and responsive chains; synthesis of the starting monomers; achievement of polymer receptors, advanced purification, structural characterization and physico-chemical behavior investigation; establishing structure-property correlations; processing of polymer structures in the desired smart materials and the proof of electrochromic, ionochromic or photochromic response; developing polymer structures with multifunctional chromic response to two or even three different stimuli, according to the philosophy "our products of tomorrow need to do more with less"; and assessing the technological potential based on the performance and application demands

Abstract:

EngDSSC project fully addresses the main objective - Secure, Clean and Efficient Energy of ENERGY Theme in Horizon 2020. In this multidisciplinary, joint project, related to the very hot topic of solar energy conversion, two partners will work on dye-sensitized solar cell (DSSC) technology, the leading photovoltaic technology among the 3rd solar cells generation. The aim of this project is to obtain a competitive DSSC prototype by molecular engineering of new sensitizers. To this goal, the DSSC configuration will be engineered using our strong know-how in chemistry and physics. To achieve a high efficiency DSSC, new molecularly engineered dyes, cell design and technological approaches will be developed. The overall work plan comprises activities ranging from the material design (TRL2) to the DSSCs prototype validation (TRL4). The new dyes combine structural features such as: a phenothiazine- or phenoxazine-substituted triarylamine as donor moiety, a π-linker and a cyanoacrylic acid as anchor and electron acceptor. Two approaches will be used: a donor in a cone-shaped configuration with strong push strength and two or three anchoring groups on TiO2 surface. The specific targets are the optimization of the push-pull dyes by our synthetic methods, their structural, photo-optical and electrochemical characterization, HOMO/LUMO levels and energy bandgap evaluation, so as to get the best sensitizers for DSSC manufacturing. Validation of the energetic compatibility between the cell’s elements, proof of the charge transfer, finding the best solution for TiO2 functionalization are the key activities whereupon the technology for DSSCs prototype fabrication will be developed. The recombination mechanisms, quantum efficiency and cell efficiency will be evaluated. As last activity, cell optimization by hole transport modulation and tuning of both the functionalization solution and electrolyte composition. The goal is to go beyond 5% efficiency, a key objective of the project.

Abstract:

The present consortium (“Petru Poni” Institute of Macromolecular Chemistry – PPIMC Iasi, Stefan cel Mare” University – USV, Suceava and APEL LASER SRL) aims to work together on a multidisciplinary joint project around a very hot topic regarding optoelectronics: white organic light emitting diodes (WOLED). In the context of the global warming, several governments took measures to promote better energy efficiency through advanced lighting technologies. Within this context, European Union set new energy efficient requirements for the lamps produced starting with September 2009, the traditional incandescent and halogen bulbs being gradually eliminated from the market. WOLED lamps are recommended as alternatives to the conventional incandescent bulbs. This is the reason why, in the last years, the thermally activated delayed fluorescence emitters consisting of strong donor-acceptor organic molecules have become highly attractive, in particular due to their applicability for low energy consuming electro-luminescent devices such as WOLEDs. The aim of this project is to obtain an OLED configuration able to be competitive on the Romanian market and not only. To achieve this target, WOLED configuration is thought according with the hottest researches within WOLEDs field and comprises original elements designed to improve the commercially WOLED performances. This includes combined efforts in chemistry, physics and engineering towards the obtaining of new materials, new device concepts, and new technological approaches and to a deeper understanding of the involved basic processes that are determining the devices performance, reliability and durability. The general aim is to reduce the cost, increase the performance and improve configurability, scalability, adaptability, reliability and self-adjusting capabilities of the integrated electronic, optoelectronic and photonic components. To realize a WOLED with increased performances, we propose the obtaining of a new hybrid material as emissive layer, being composed of two thermally activated delayed fluorescence compounds, e.g., green and red emitters, respectively, dispersed as nanometric droplets/nanocrystals into a fluorescent, blue emitting matrix. After varying the molar ratio between the three components, a white light emission will be achieved. To assure the best purity of the hybrid material components, the low molecular weight compounds will be obtained in form of single crystals, while the polymers will be synthesized through electropolymerization. The hybrid material and its components will be structurally confirmed and the film forming ability, electrochemical, optical, electro-optical, mechanical and morphological properties will be determined with the aim to choose the most appropriate material for WOLED configuration. The materials with optimal balance of properties, i.e., good flexibility, white emitting and good quantum efficiency will be selected, and a simulation of the WOLED configuration will be done based on their electrochemical characteristics (HOMO/LUMO levels, band gap, and reversibility of oxidation and reduction processes). The results of simulation process will allow us to choose an optimal configuration to determine the WOLED maximum performances. The electrodes and the substrate with the proper characteristics will be obtained in our laboratories, thus avoiding the eventually inadequacies caused by the use of commercial products. An original element of the proposed configuration is the creation of a new substrate with a refraction index close to air by dispersing liquid crystals in a polymer matrix.
